Learning juggling: throwing versus bouncing for college students
TuJugling: a Cluster-randomized Cross-over Trial Comparing Two Juggling Learning Methods in College Students
This trial will test whether practicing juggling by throwing balls in the air or by bouncing them off the floor helps college students learn juggling faster and whether the order of the two methods matters.

What this trial studies
University students enrolled in a motor games course will learn juggling using two different methods—throwing the balls in the air or bouncing them off the floor—during two consecutive 4-week practice periods separated by a 1-week break. Participants are assigned to do one method first and then switch, and performance is measured from video at baseline, after period 1, and after period 2, with the primary comparison focused on results after the first period to limit carryover. Questionnaires about mood and flow are collected at each assessment, and exploratory measures include handgrip strength and brief computerized cognitive tasks at baseline and the final visit. Video recordings are scored using anonymized study identifiers to quantify juggling performance over time.
Who should consider this trial
Good fit: Ideal participants are students aged 18 or older enrolled in the Motor Games course who can give informed consent and agree to the study assessments.
Not a fit: People with injuries or medical conditions that prevent safe juggling or with uncorrected visual impairments that stop them from tracking the balls are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the results could help instructors choose a more effective teaching method and improve how quickly students acquire juggling skills.
How similar studies have performed: Previous motor learning research shows practice improves juggling and that practice format can influence skill acquisition, but direct comparisons of throwing versus bouncing methods are limited.
